(See also [p. 120].)
[2314]. Lieuvain’s needle lubricator, with bent needle for oiling a crank pin. The latter has a pad attached, which rubs in passing the bent needle and thus takes off the oil.
[2315]. Pan lubricator for crank pin, to assist oiling from an oil can when revolving.
[2316]. Crank pin lubricator. A fixed oil cup, with a pad of flannel attached; the connecting rod end having a bent plate attached, which at every revolution rubs oil off the pad into its oil cup.
[2317]. Lubricating a loose pulley on a fixed or revolving shaft by a “Stauffer” lubricator fitted to the shaft end.
[2318]. Lubricating a loose pulley on a fixed stud.
[2319]. Mode of lubricating a vertical spindle, carrying a wheel or other top gear which prevents access to the bearing.
Sight feed lubricators, show the actual feed of oil in a glass tube filled with water through which the oil passes in drops; there are many varieties.
Compound lubricators are now being introduced whose function is to supply lubricant to every joint or part of an engine or machine requiring it, by automatic feed action from one reservoir.
[2320]. Syphon wick lubricator.
[2321]. Automatic lubricator, with intermittent feed. The revolving spindle is driven from the engine by a ratchet and pawl motion, and has a recess in it which in revolving delivers its contents of oil into the tube below.
[2322]. Spring piston lubricator.
[2323]. Gland, with oil well.
